An Infinite God

"A God who let us prove his existence would be an idol” - Dietrich
Bonhoeffer

I wonder at the great desire that seems to be in the church to be able to prove the existence of God. Is this drive a result of a commitment to some aspect of modernism? While I think it certainly did not originate as a result of the enlightenment since it was prominent in the church centuries before, but I would guess it was definitely reinforced over the following centuries.
The world today is looking for a God that is bigger than our thoughts, a God who is full of mystery, beyond our frail attempts to define and prove. And I am forced to wonder at how to offer the world an infinite God in the frail packaging of humnanity?
